Hi there.
Can you provide a bit more information about the project you want to develop? What is it about, what are requirements for it, when the project starts, how long is it going to last...?
I have on Loom and on sites where I have clients that I am working/have worked for ( can provide URL for proof and their ratings of my job). I have repositories where I keep and recycle code whenever I can. Time is precious for both sides. Have cloned Uber, Instagram, Twitter and Snapchat and most of their features I offer for free for people to use. For what I understand, you need a developer that understands API calls and integrating them with existing ones on the back-end, right?
It would be nice if you could provide greater detail about the project before we continue further. It would be a huge time-saver. Anyway, feel free to contact me anytime.
